Liverpool and Aberdeen are amongst the cities that have seen dozens of vehicles off the road since last summer due to fueling problems and high maintenance costs
Isn’t there a case for hydrogen as jet fuel? It has the potential to be much lighter than batteries, which shouldn’t be surprising given that it uses oxygen from the atmosphere.
Hydrogen as a substance is light, but the equipment to make it viable isn’t. The kind of high pressure tank required to keep it under high enough compression to make the energy density viable, with walls thick enough so that it doesn’t embrittle and explode specularly after a few weeks’ usage, is hugely heavy.
